Methods for determining the zone of avalanche initiation using tools are proposed ArcGis 10.4.1. The process of creating a raster of the slope of heights and later on the territory itself for dividing them into existing gradations is described. Demonstrated the process of determining the area of avalanche foci and determining the boundaries of the avalanche collection. The areas of avalanche origination within the avalanche collection have been corrected. The method of creating a map of the exposure of slopes in order to identify the area of accumulation and drift of snow, its dynamics and characteristics of snow melting is shown. Based on this, it becomes possible to determine the maximum height of avalanche initiation and the range of the avalanche ejection.
